The invention discloses a preparation method for a low-self-noise stainless steel wire. The diameter of the low-self-noise stainless steel wire is 5.9-6.1 mm. The low-self-noise stainless steel wire comprises, by mass, 0.01%-0.03% of carbon, 13%-17% of chrome, 4%-8% of nickel, 0.1%-0.12% of copper, 0.4%-0.5% of magnesium, 1%-1.2% of manganese and the balance iron. According to the low-self-noise stainless steel wire prepared through the preparation method, the abrasion resistance and the corrosion resistance of the stainless steel wire are greatly improved; machining and forming are easy; a certain damping performance is achieved; the self noise is low; the problems that a steel wire is prone to being corroded, rusted and abraded and large in noise are well solved; and the service life of the low-self-noise stainless steel wire is prolonged.
